java - 如何在 LibGDX 项目中显示插屏广告？

Question

找了一个Flappy Bird的GitHub项目，稍微改了一下。我成功实现了 AdMob 横幅广告。

但现在我还想要一个在游戏结束时弹出的插页式广告(当然不是每次)所以这是我的 GitHub 项目:https://github.com/DaFaack/FlappyBibi

请向我解释如何操作，因为我在互联网上找不到很好的解释。

我想在 run() 方法中显示广告。您可以在核心包 -> GameplayScreen.java 文件 -> renderPlaying() 方法和 run() 方法中找到它。

这就是我所说的方法:

    private void renderPlaying() {
        if (justTouched) {
            bird.jump();
            justTouched = false;

        }
        updatePipePairs();
        gameplayStage.act();
        uiStage.act();
        checkCollisions();
        if (bird.getState() == Bird.State.DYING) {
            stopTheWorld();


            RunnableAction playWooshAction = Actions.run(new Runnable() {
                @Override
                public void run() {
                    com.pentagames.flappybibi.Assets.playWooshSound();

//Here I want to display the Interstitial Ad!

                }
            });

当游戏结束时，我必须做什么才能显示插页式广告？

这是我的 AndroidLauncher.java 文件:

这是我第一次使用 LibGDX，如果你能解释一下如何在这个项目中实现插页式广告，那就太好了。

抱歉我的英语不好。

Answer 1

您已经集成了横幅广告，因此无需在您的项目中注入(inject)依赖 Artifact 。

按照这些步骤进行插页式广告集成。

1. AndroidManifest.xml

   为插页式广告创建一个AdActivity条目

   <activity android:name="com.google.android.gms.ads.AdActivity"
             android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
             android:theme="@android:style/Theme.Translucent" />
   

2. 在核心模块中创建一个接口(interface)

   public interface AdService {
   
      boolean isInterstitialLoaded();
      void showInterstitial();
   }
   

3. 创建FlappyGame 类的参数化构造函数

   public AdService adService;
   
   public FlappyGame(AdService ads){
        adService=ads;
   }
   

4. 为您的 AndroidLauncher 类实现 AdService 接口(interface)

   public class AndroidLauncher extends AndroidApplication implements AdService {
   
       private static final String AD_UNIT_ID_INTERSTITIAL = "ca-app-pub-XXXXX/XXXXX";
       private InterstitialAd interstitialAd;
   
       @Override
       protected void onCreate (Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
   
            ...
            View gameView=initializeForView(new FlappyGame(this), config);
            ...
   
            interstitialAd = new InterstitialAd(this);
            interstitialAd.setAdUnitId(AD_UNIT_ID_INTERSTITIAL);
            interstitialAd.setAdListener(new AdListener() {
                 @Override
                 public void onAdLoaded() {}
   
                 @Override

5. GameScreen 类

   RunnableAction playWooshAction = Actions.run(new Runnable() {
           @Override
           public void run() {
               com.pentagames.flappybibi.Assets.playWooshSound();
                game.adService.showInterstitial();
           }
   });
